The U.S. has the highest number of traffic deaths among wealthy countries, with more than 38,000 deaths per year between 2015 and 2019. The death rate is more than double the average rate in other wealthy countries. Vehicle crashes are among the leading causes of death in the U.S. But it doesn’t have to be this way. We can design or redesign streets to make people drive more slowly or to discourage driving altogether. We can invest in better public transit, including subways and buses with dependable, on-time service. And we can change zoning laws to allow denser housing and mixed-use developments, so people can live closer to where they work, attend school or socialize. These are changes that even the largest, most sprawling cities can and should implement.
